Most gamma-ray bursts—the brightest, most powerful explosions in the universe—are tracked back to the deaths of massive stars. But a new discovery suggests that such enormous explosions can come from ...

Billions of light years away in a remote part of the universe, two neutron stars – the ultradense remnants of dead stars – collided. The catastropic cosmic event sent light and particles, including a ...

"The gamma-ray burst traveled through intergalactic space at the speed of light for eleven billion years, during which time the Sun and the planets were born." — Timothy Ferris, in the film version of ...

Add Yahoo as a preferred source to see more of our stories on Google. The orange dot at the center of this image represents a powerful explosion that repeated several times over one day. - A. Levan, A ...

When faraway stars explode, they send out flashes of energy called gamma-ray bursts that are bright enough that telescopes back on Earth can detect them. Studying these pulses, which can also come ...

A recently detected flash of energy appears to have emanated from the wreckage of colliding galaxies, according to an international team of astronomers led by Penn State scientists. The burst, known ...

Astronomers are puzzled after detecting a mysterious repeating series of gamma-ray bursts outside our galaxy. The unknown phenomenon repeated several times over the course of a day, an event unlike ...

Back in October of 2022, astronomers around the world were baffled and awed by the largest gamma-radiation burst we've ever recorded. The burst was so powerful, in fact, that it has been nicknamed the ...

Astronomers at Rice University in Houston have discovered that the rate at which a gamma-ray burst cools might be used to calculate the distance of that burst. Their findings are being presented today ...

NASA’s James Webb Space Telescope reveals new clues about a mysterious cosmic explosion that defies expectations. Researchers are investigating an unusual event in deep space that has left scientists ...

Astronomers are trying to understand what caused a series of gamma ray bursts, or GRBs — the most powerful explosions in the universe. These energetic bursts are typically unleashed by the incendiary ...
